Definitions

  • the invention relates to a basin in a sewage plant according to the preamble of claim 1.
  • Retention basins, flood relief, rain basins etc., in wastewater plants serve to temporarily store the amount of wastewater that exceeds the capacity of the sewage treatment plant in the event of a major rain event and to later discharge it to the sewage treatment plant. If the storage capacity of the pool is no longer sufficient, the amount of water flowing in must be fed directly to flowing or standing water.
  • an overflow channel can be arranged on the side of the retention basin, the overflow edge of which faces the basin essentially at the level of the maximum possible water level in the basin.
  • a baffle in front of the overflow channel.
  • baffle wall is floating and to use it on swivel arms which are articulated on the overflow channel side.
  • the object of the present invention is to form a channel lying between the basin and the overflow channel, in which means are provided which prevent the entry of floating impurities both at the beginning and during a rain event.
  • the wall By arranging a wall in a channel upstream of the overflow channel, the wall can be firmly connected to the building or can be designed as part of the building. If the wall is pulled up to the ceiling of the basin or is suspended from it, the space above the overflow channel and the associated drainage channel and the basin space for smells and also access for people can be separated.
  • the wall can also be designed such that it can be raised and lowered in order to retain any solid bodies that have been washed in when the channel is filled, on the pool side of the lowered wall.
  • a line connecting the channel to the basin which is formed on the pool side by a flap that can be closed with rising water level in the pool, serves to empty the channel when the water flow into the pool decreases and to return sedimented substances to the pool.
  • an overflow channel 7 is arranged on the right basin wall 5. This can be attached to the wall 5 or be part of the wall 5. On the pool side, the overflow edge 9 of the overflow channel 7 is at the height h 1 .
  • the overflow channel 7 is connected to a drain line 11, which leads to the receiving water or into open water.
  • a drain line 11 In the left basin wall 13 there is an inlet opening 15 through which water is supplied to the basin 1.
  • a collecting trough 17 can be let in, which is connected at the front by a line 19 to a sewage treatment plant.
  • a channel 21 is arranged on the basin side of the overflow edge 9, the overflow edge 23 of which lies at the height h 2 .
  • the overflow edge 23 of the channel 21 is somewhat lower than that of the overflow channel 7.
  • the channel 21 can be connected to the sewage plant at the end by a closable connecting line 25 for emptying.
  • a wall 27 extending over the entire length of the channel 21 is arranged between the two overflow edges 9 and 23. The lower edge 29 of the wall 27 is below the height h 2 , ie it dips into the cross section of the channel 21 when it is filled with water.
  • the design of the basin 1 according to FIG. 2 differs from that in FIG. 1 in that the wall 27 on the ceiling 31 of the basin 1 is attached or abuts against it. Furthermore, instead of the connecting line 25, which leaves the end of the channel 21, a bushing 33 leads from the channel 21 into the basin 1.
  • the feedthrough 33 can be closed by a flap 35, which lies in front of the feedthrough 33 with increasing water level and thus prevents the passage of water from the channel 21 into the basin 1.
  • the wall 27 is arranged to be vertically displaceable or pivotable, so that it can sink to the bottom of the channel 21 when it is empty and thus prevents solid bodies 37 floating from the basin 1 under the bottom edge 29 of the basin 1 when the channel 21 is filled Wall can get into the overflow channel 7.
  • the wall 27 can be articulated to pairs of levers 39 and be designed to float, or it can be displaceably guided by a vertical guide (not shown) attached to the side walls of the pool.
  • a line 41 is provided for the passage 33 through the channel 21, which projects beyond the channel 21 downwards and can be closed by a valve 43, which only allows water to enter the channel 21 when the valve 43 is below the water level h 3 lies and thereby no impurities can get into the channel 21 through the line 41.
  • the valve 43 can of course also be used for emptying the channel 21, especially when there is a risk of frost in winter.
  • Floating solids 37 which are introduced into the basin 1 with the water, are retained by the wall 27 and cannot flow below the lower edge 29, over the overflow edge 9 into the overflow channel 7 and from there into a receiving water or into a body of water. So that the wall 27 in the channel 21 is always functional, the channel 21 is preferably always filled with water, or it is filled up immediately when a major rain event occurs.
  • the channel 21 is filled with service water up to the overflow edge height h 2 .
  • the water in the basin 1 flows through the line 19 to the sewage plant in a predefinable amount per unit time.
  • Sediments and the floating solids 37 collect in the trough 17 and can be fed from there to the wastewater treatment plant.
  • the sediments that remain in the channel 21 can also be fed to the sewage system by opening the connecting line 25.
  • the wall 27 extends to the ceiling 31, it can be achieved that the space of the basin 1 and the space above the overflow channel 7 are separated from one another for odors.
  • the vapors of volatile substances that have been introduced into the basin 1 cannot get out of the building through the overflow channel 7 and the drain line 4.
  • the wall 27 forms together with the channel 21 an olfactory siphon.
  • the wall 27 also serves as access security for the operating personnel.
  • the channel 21 is emptied automatically after the water level has dropped, because as soon as the water level within the channel 21 is above that in the pool 1, the static water pressure ensures that the flap 35 is opened and the water in the channel 21 is returned to the pool 1 and can flow from there through line 19 into the sewage treatment plant.
  • the aim is that the channel 21 is always filled, on the one hand to serve as an odor siphon and to prevent solid bodies from being washed under the wall 27 at the beginning of the rain event.
  • the water must be drained from channel 21 in winter to prevent frost damage.
  • valve 43 allows water to enter the channel 21 at the moment when the water level h 3 has reached the valve 43 and therefore none on the valve
  • Water floating solid 37 can be flushed through the line 41 into the channel 21. It is also not possible to pass solid bodies under the wall 27 if the latter can be moved vertically as shown in FIG. 3 and only rises when the level within the channel 21 has reached a certain height, which is sufficient around the wall 27, which is designed to be floatable is to give a boost. As a result, floating solid bodies 37 are retained on the pool side.
